Over the years, operating systems have sought to be more efficient, which is why it is vital that the use of main memory such as ram be as intelligent as possible, so that operating systems are more efficient.
Segmentation is a process of dividing the program into logical units, such as sub functions, arrays, variables, etc., making it possible to have processes divided into pieces so that it is easy to access each of the processes that this leads to its execution. Segmentation allows the programmer to contemplate the memory as if it had several address spaces or segments. References to memory consist of an address of the form segment number - offset.
Pagination is a technique where memory space is divided into physical sections of equal size, called page frames. The programs are divided into logical units, called pages, that are the same size as the page frames. In this way, an information page can be loaded in any page frame. The pages serve as an information storage unit and transfer between main memory and auxiliary or secondary memory. Each frame is identified by the frame address, which is in the physical position of the first word in the page frame.
Answer:Protects the local network from outside access
Explanation:Proxy is a type of serves as the mediator in computer network for connecting the network with the user system. These servers are responsible for maintaining the security against any unauthorized access in the system or internet,privacy and other functions.. It helps in protecting the whole network connection by taking the control at the servers .

Answer:
<u>Proportion </u>is the aspect in design theory that describe the relationship of one object to another object in size.
Explanation:
Proportion is an important aspect in design theory in terms of size. It refers to the relationship between object of the design in terms of size. The relation between size of different object in design theory can describe as, if the size of one object increases or decreases, it may leads to change in size of other object. It is called proportion.
If the size of one object increase with the size of other object, the relation is called direct proportion. If the size of one object decrease with the increase in size of other object is called inverse proportion.
Answer:
d) y=x++
Explanation:
In all 3 statements:
y= ++x;
y=x=5;
y=5;
The value of y is equal to 5.
However in the statement y=x++, the value of 5 is equal to value of x prior to the increment operation. The original value of x was 4. So the value of y will be 4. Note that after the statement execution, the value of x will be updated to 5. In effect y=x++ can be visualized as a sequence of following steps:
x=4;
y=x;
x=x+1;
